Cold Storage


PlastiSpan® Insulation is used in Cathedral Ceiling, Continuous Insulation, Exterior Foundation, Interior Basement Walls, Basement Floor, Under Slab, Hydronic, EIFS and handi-pac Packaging & Display.


PlastiSpan® insulation board is ideal for use in wall and roof assemblies
used to enclose cold storage space for cooling and/or storing food,
flowers, and other commodities at temperatures ranging from normal
room temperature 20ºC (68ºF) down to cryogenic temperatures -100ºC
(-148ºF). As the surface temperature decreases, the quality of
construction and care required becomes more critical.

PlastiSpan insulation is well suited for use as insulation of cold storage
space because of its excellent thermal resistance, dimensional stability,
chemical inertness and durability. As well, it is a plastic foam insulation
with a closed cellular structure that provides low water vapour permeance
and water absorption characteristics.

PlastiSpan insulation board is only one component in the construction.
All components of construction as well as the mechanical equipment for
cooling and/or humidifying must act together to achieve a system that
will enclose space and hold it at the desired temperature for extended
periods of time without any deterioration. For instance, it is recommended
that any lumber incorporated into cold storage construction be pressure
treated with wood preservative.

2PlastiSpan 25 insulation meets or exceeds CAN/ULC-S701, type 3 and ASTM C578, type IX.
3PlastiSpan 30 insulation meets or exceeds CAN/ULC-S701, type 3 and ASTM C578, type IX.
4PlastiSpan 40 insulation meets or exceeds CAN/ULC-S701, type 3 and ASTM C578, type XIV.
5WVP values quoted are maximum values for 25-mm thick samples with natural skins intact. Lower values will result
for thicker materials.
6The water absorption values are applicable to specific end-use design requirements only to the extent that the end-use
conditions requires submersion under a head of water for an extended period of time.
